Vaso Čubrilović (born January 14, 1897 in Gradiška, Bosnia and Herzegovina, Austro-Hungarian Empire - died June 11, 1990 in Belgrade, Serbia) was a Bosnian Serb politician and scholar. He was a student in Sarajevo, when Danilo Ilić recruited him and his friend, Cvjetko Popović, to help assassinate Archduke Franz Ferdinand of Austria. His brother, Veljko Čubrilović, was also involved in the plot. Like Princip, he was a member of Young Bosnia, an underground organisation with the aspiration of the creation of a southern Slav state free from both Ottoman and Hapsburg influence.
Assassination of Archduke Ferdinand
On Sunday, 28 June 1914, Franz Ferdinand and Sophie, Duchess of Hohenberg were assassinated. The fatal shots were fired by a Bosnian Serb, Gavrilo Princip, who wanted Bosnian unification with Serbia and independence from the Austro-Hungarian Empire. Princip and Nedeljko Čabrinović were captured and interrogated by the police. They eventually gave the names of their fellow conspirators. Muhamed Mehmedbašić managed to escape to Serbia. Vaso Čubrilović, Danilo Ilić, Veljko Čubrilović, Cvjetko Popović and Miško Jovanović were arrested and charged with treason and murder.
Eight of the men charged with treason and the murder of Archduke Franz Ferdinand were found guilty. Under Austro-Hungarian law, capital punishment could not be imposed on someone who was under the age of twenty when they had committed the crime. Nedjelko Čabrinović, Gavrilo Princip and Trifko Grabež therefore received the maximum penalty of twenty years. Vaso Čubrilović got sixteen years and Cvjetko Popović thirteen years. Miško Jovanović, Danilo Ilić, a member of the Black Hand, and Veljko Čubrilović, who helped the assassins kill the royal couple, were executed on 3 February 1915.
He wrote a letter to his sisters from Zenica Prison explaining how it came about that he was involved in one of the most notorious assassinations in history and of the fall out - "When I was arrested and detained at Dubica, I admitted giving it [my bomb] to Ivo [Kranjcevic] - Ilic had already betrayed Djukic and Popovic. As you can see, we all betrayed each other. [-] In my opinion the assassination turned out well, considering who they gave the job to. In any event, it wasn't our intention to cause a world war, and we truly believed just a couple of Serbian officers sent us the weapons." 
Vaso Čubrilović was released when the Allies defeated the Central Powers in November 1918. He became a teacher in Sarajevo and subsequently a professor at the University of Belgrade. He advocated the expulsion of Kosovar Albanians from Kosovo in a 1937 memorandum.
In the closing stages of World War II he wrote another memorandum entitled "The Problem of Minorities in the New Yugoslavia," concluding that "Democratic Federal Yugoslavia can be sure of peace and development only if it is ethnically pure and has settled once and for all the question of minorities, which are a cause of quarrels between it and the neighbouring states." After the war he served as Minister of Forests in the Federative People's Republic of Yugoslavia.
He died in 1990, the last surviving participant in the conspiracy to assassinate the Archduke.
